Two chambers 23 are respectively mounted in the chambers 7, and have their side Walls and lower ends spaced from the side walls and bottoms respectively of the chambers 7, the upper ends of said chambers 23 being respectively fastened to the bottoms of the chambers 1. Respectively fitted in the lower ends of the chambers 23 are two vertical tubes 24 having their open upper ends preferably extending above the bottoms of said chambers 23. The lower ends of the tubes 24 are closed with the exception of small drip openings 25 provided therein. The lower end portions of the chambers 23 incline downwardly to the tubes 24, such inclined portion having small drip openings 26 therein. The openings 25 and 26 discharge into the chambers 23.

The chambers 1 are respectively provided with outlets 27 comprising two vertical tubes fitted in the bottoms of the chambers 1 and respectively discharging into the chambers 23. The tubes 27 preferably project above the upper sides of the bottoms of the chambers 1. I

The bottom portion of each chamber 1 has a U shaped opening 28, the horizontal arms 29 of which are disposed at opposite sides respectively of the adjacent tube 27 and conductor 22, Fig. 2.

The portions of the bottom of each chamher 1 at the inner sides ofthe arms 29 of the opening 28 are preferably serrated, as indicated by 30, Figs. 1 and 2, the bottoms of the serrations being, preferably, slightly higher than the upper end of the outlet tube 24 adjacent thereto. The bottom at the inner side of the opening 28 and at the outer end of the adjacent rows the serrations 30 is turned upwardly as designated by 31 to form a dam the upper edge of which is higher than the upper end of the adjacent outlet tube 24.

Extending vertically in the outer end portions respectively of the chambers 1 are two tubes 32, the upper ends of which are each provided with vapor intakeopenings 33, and the lower ends of which are respectively fastened in the bottoms of the chambers 1 and respectively communicate with the upper ends of two downwardly and outwardly extending tubes 34, the lower ends of which are respectively connected to two elbows 35, which are respectively connected to two pipes 36, theother ends of which are respectively connected by two elbows 37 with two horizontal pipes 38. Said pipes 38 are respectively connected to two alined arms of a cross joint 39, Figs. 1, 2 and 4.

The other two arms of the cross joint 39 have respectively mounted in them a pipe 40 and a removable screw plug 41, Fig. 3.

The other end of the pipe 40 has mounted on it an elbow 42 on which is fitted any suitable burner, as the burner 43, Fig. 3 and Fig. 4, which is provided with, in its upper end,

a small discharge opening 44. If it is deing connected with a source, not shown, of

air under pressure, Fig. 12.

The burner 43 is under and spaced from and in axial alinement with the deflector disk 3.

To guard the tubular extensions 8 from the intense heat of the flame from the burner 43, there are provided two guarding tubes 46 which encircle respectively and are spaced from the tubular extension 8. The upper ends of the tubes 46 are supported by being respectively attached to the bottoms of the chambers 7.

As a further protection to the over heating of the tubular extensions 8, there are provided two deflector plates 47 disposed respectively at and attached to the sides of the guarding tubes 46 next to the burner 43.

For releasably fastening together the rings 19 and 20, there are provided two internally threaded couplings 48, Figs. 1, 3 and 4, which are respectively fitted on the threaded rings 19 and respectively bear on the upper sides of the rings 20, thus tightly clamping the rings 19 to the rings 20.

In the operation of the burner mechanism, fuel oil entering the pipe 12 passes by way of the T 13 to one of fuel conductors 22 through the pipe 14, elbow 18 and members 19 and 20. Fuel oil also passes from the T 13 to the other fuel conductor 22 through the pipe 15, union 16, pipe 17, elbow 18 and members 19 and 20. I

The fuel from the conductors 22 is discharged into the chambers 1 respectively, which, as are the chambers 7 and their tubular extensions 8, are initially heated by flames from burning oil placed in the drip pan 11.

The fuel thus discharged into the heated chambers 1 is partly vaporized, the vapor passing to the burner 43 through the tubes 32 and 34, elbows 35, pipes 36, elbows 37, pipes 38, cross joint 39, pipe 40 and elbow 42. The vapor thus discharged from the burner 43 is ignited and the resulting flame striking the deflector 3 continues the heating operation.

Heavier portions of the fuel oil discharged into the chambers 1 and not vaporized there in, collect on the bottoms of said chambers 1 and overflow at the upper ends of the outlet tubes 27, and are discharged therethrough into the chambers 23, which are heated, due to their being in the heated chambers 7.

Some of the said heavier portions of the fuel oil are vaporized in the chambers 23, the vapor passing upwardly through the tubes 27 into the chambers 1, and thence through the inlets 33 into the tubes 32. The'liquid oil in the chambers 23 drips therefrom through the openings 25 and 26 into the chambers 7, where some of it is vaporized and passes therefrom through the U shaped openings 2829 to and through the chambers 1 and inlet openings 33 into the tubes 32.

The heaviest portions of the oil, which are not vaporized in the chambers 7 'flow downwardly into the tubular extensions 8, wherein they are vaporized and pass therefrom through thechambers 7 openings 28- 29 and chambers 1 into the inlet openings 33, from which the vapor passes, as described to the burner 43.

By reason of location of the chambers 23 within the chambers 7, and the tubular extension 8 being guarded from the intense heat of the flame, the heavy oil is gradually heated and vaporized, thus preventing frying of the oil and the formation of carbonaceous material on the inner walls of the chambers 1 and 7 and tubular extensions 8. Even after long use my improved burner mechanism has a very small amount of carbonaceous material deposited on the inner walls of the chambers, and such can be easily and quickly removed with hot water and without the usual use for this purpose of a blow torch, the screw plugs 2 being removed for the ad mission of the hot water into the chambers 1, 7 and 23.

In case that by chance an extremely heavy greasy oil is fed into the chambers 1, such as crank case oil, and the chamber openings 25 and 26 become clogged, such oil will fill the chambers 23 and will over flow into the chambers 1 through the tubes 27 until its level in the chambers 1 reaches the level of the arms 29 of the opening 28, after which the oil will pass into the chambers 7 through the notches between the serrations 30, following which vaporization of the oil would occur in the chambers 7 and their extensions 8, the resulting vapor passing upwardly through the U shaped openings 28-29 into the chambers 1, and thence through the openings 33 into the outlet tubes 32, the vapor then passing by the paths already described to the burner 43.

In Figs. 5 to 9 is illustrated a form of burner of my invention which may, with some fuels, be advantageously substituted for the burner 43 shown in Figs. 1, 3 and4.

In the form of burner shown in Figs. 5 to 9, the lower end thereof has a pipe 49 the lower end of'which is fitted in the elbow 42, the upper end being fitted in the lower end of a pipe 50, on the upper end of which is tted an upwardly flaring nozzle 51 provided on its upper edge with projections 52. Above and normally spaced from the proa convex under side.

jections '52 is a removable cap 53 which has A horizontal hole 54 extends through the upper end of the cap 53, which hole is adapted to receive a poker or other rod, not shown, by which the cap 53 may be axially oscillated, as will be described.

The under side of the cap 53 has a central vertical hole in which is tightly fitted the upper end of a vertical rod 55 the lower portion of which is slidably fitted in a central vertical hole 56, Fig. 9, of a bridge portion 57 of a short vertical tube 58 which is tightly fitted in the pipe 50.

Acoil spring 58 encircles the rod 55 and rests at its lower end on the top of the bridge portion 57. The upper end of said coilspring 58 supports the lower end of a spacing sleeve 59, on the upper end of which rests the under side of the cap 53, Fig. 6.

In the use of the burner shown in Figs. 5 to 9, the vapor will pass from the elbow 42 which supports it through the pipe 49, pipe 50, bridge tube 58 into the nozzle 51 from which it will be discharged laterally in a circular sheet between the cap 53 and the nozzle 51.

When it is desired to clear the lower part of the cap 53 which is just above the upper edge of the nozzle 51 of carbon deposits, a poker or rod is inserted into the hole 54 and caused to depress the cap 53 onto the projections 52, after whichthe cap is oscillated, thus causing the said projections to scrape a circular portion of the under side of the cap, thereby removing the said deposits so as to afford a clear passage between the cap and the nozzle 51. Upon removing the poker or rod from the cap 53, the coil spring 58 will, through the spacing tube or sleeve 59,

lift the cap 53 clear of the nozzle projections 52, to the position shown in Fig. 6. By increasing or decreasing the length of the coil spring 58, the cap may rest at different operatinlg positions above the nozzle 51.

In igs. 10 and 11 is shown another burner of my invention adapted for use as a substitute for the burner 43. This burner has a tubular shank 60 the lower end of which is fitted on the upper end of a pipe '61, the

lower end of which is adapted to be mounted in the elbow 42.

The said tubular shank has extending from its upper end a plurality of tubular radial arms 62, the outer ends of which are respectively provided with outlet slots 63. Each arm 62 at its outer end and upper side has a lip 64 which extends outwardly beyond the lower lip 65 of the arm.

The projecting issuing from the arms 62 passing upwardly as quickly as it would with the lips 64 and 65 having like projection.
